Project History & More Info:
These TV's are old, extremely heavy, and are breaking down on people everywhere. They usually cost more to fix than they could be sold for, so people are begging you to come take them away for free!
I usually find mine on the classified ads under the "free" section, but they are also common on the sides of streets and alleyways where people have left them for trash.
PLEASE NOTE: These lenses are found in "rear-projection" televisions and not all are the same. Some are discolored, and some concentrate to a beam rather than a point. The particular screen I found was a crystal clear acrylic lens that focused to a point. It may have been luck that I found it on my first try, because 3 TV's after that all had lesser grade lenses, but still produced enough heat to melt zinc. Just FYI! You can also see http://youtu.be/xExXjXm0YV0 for examples of these different lenses.

I use a large fresnel lens to test the effect of concentrated sunlight on a solar cell. To keep the solar cell cool I immerse it in mineral oil. I measure the voltage, current and the temperature. But I also test it without the cooling and sure enough, the solar cell is destroyed by the concentrated sunlight. The fresnel lens is one I got from a rear projection TV.

This is the same solar stirling engine with a strong Fresnel Lens. The steel wool adds power to the stirling displacer piston as the light has a good focal target INSIDE the glass chamber Dramatically increasing efficiency. This is very important as most Stirling Engine lose 50% of their heat into the surrounding air. A vacuum would be even better. Also, because the glass chamber easily removes with a rubber O ring fitting, air can be replaces with a custom heat exchange gas.

Fresnel Lens solar water filtration systems offer an off grid option to clean water This solar distiller can deliver .5 GPH The Fresnel lens concentrates sunlight to a common focal point that creates a steam boiler allowing for rapid distillation with the sun.

If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water. Distilled water is not magic, if you add a splash of milk to tea made with distilled water, you now have 10x the calcium of regular mineral water.
http://www.eves-best.com/distilled-water-myths.htm
Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. For the rest of the world who usually ingest 15x the sodium recommended, distilled water leaches salt first. ONLY IF you are salt deprived (extremely rare) will distilled water leach excess potassium and or calcium.
You would need to drink about 2 gallons in 10 hours for there to be a problem.
If heavy sweating, water of any kind is only a thirst quencher or temporary fluid fix. Most people can afford 7 pounds of sweat (near gallon) replaced with only water before electrolytes become an issue. At that point, electrolytes are needed regardless of water type ingested. Mineral water has very small trace minerals and represents a small fraction of where K, Na, Ca is absorbed in the body. For you to get your average daily requirements of Ca and K from water alone, the water would taste terrible.

GIANT FRESNEL LENS TROUGH MIRROR

The max power was 20 watts, pretty weak. The treadmill motor produced about 25v no load and was able to get the GTI working:-) BUT it did not last long. This should be much stronger. I rushed today because it was our first REAL day of sun in over 1 month.

Fresnel lens

The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. A Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances.

History

The idea of creating a thinner, lighter lens by making it with separate sections mounted in a frame is often attributed to Georges-Louis Leclerc, Comte de Buffon. The marquis de Condorcet (1743–1794) proposed grinding such a lens from a single thin piece of glass.
French physicist and engineer Augustin-Jean Fresnel is most often given credit for the development of the multi-part lens for use in lighthouses. According to Smithsonian magazine, the first Fresnel lens was used in 1823 in the Cordouan lighthouse at the mouth of the Gironde estuary; its light could be seen from more than 20 miles (32km) out. Scottish physicist Sir David Brewster is credited with convincing the United Kingdom to adopt these lenses in their lighthouses.

Solar (room)

The solar was a room in many English and French medievalmanor houses, great houses and castles, generally situated on an upper storey, designed as the family's private living and sleeping quarters. In such houses, the main ground-floor room was known as the Great Hall, in which all members of the household, including tenants, employees and servants, would eat. Those of highest status would be at the end, often on a raised dais, and those of lesser status further down the hall. But a need was felt for more privacy to be enjoyed by the head of the household, and, especially, by the senior women of the household. The solar was a room for their particular benefit, in which they could be alone and away from the hustle, bustle, noise and smells (including cooking smells) of the Great Hall.

The solar was generally smaller than the Great Hall, because it was not expected to accommodate so many people, but it was a room of comfort and status, and usually included a fireplace and often decorative woodwork or tapestries/wall hangings.

Solar (Taeyang album)

Solar is the first full-length solo album by Korean singer Taeyang, member of Big Bang. The album was released in two forms: the "Regular Edition" and the "Deluxe Edition" which is limited to 30,000 copies worldwide. The lead-single was "I Need a Girl" featuring his bandmate G-Dragon. On July 9, 2010, Taeyang's solo album Solar hit second place on iTunes' Top R&B-Soul albums chart in the United States and first place in Canada, the first time for an Asian musician. In Solar, Taeyang put much effort into enhancing his vocal skills as well as his composing, co-writing as many as four songs ("Solar", "Where U At", "Wedding Dress", and "Take It Slow") and writing lyrics for "Take It Slow".

Taeyang's first international album, Solar International, is the first ever K-Pop music release to be sold worldwide on iTunes as both an audio and video album. The audio version (complete with a digital booklet) hit iTunes stores on August 19, 2010, while the video version (bundled with bonus, behind the scenes documentaries) arrived by September 10, 2010. The audio album combines both English and Korean hits from his past and present albums including "I'll Be There", "Connection" (feat. BIG TONE), "Wedding Dress" and "I Need a Girl (feat. G-Dragon)". On August 26, 2010, Solar's International album made it to fifth place on iTunes' Top R&B-Soul albums chart in the United States and Japan, and third place in Canada.

SOVIM (Solar Variantions and Irradiance Monitor) instrument is based on an earlier instrument (SOVA) which flew aboard the European Retrievable Carrier, launched on STS-46 in 1992. It is designed to measure solar radiation with wavelengths from 200 nanometers - 100 micrometers. This covers near-ultraviolet, visible and infrared areas of the spectrum.

SOLSPEC (Solar Spectral irradiance measurements) is designed to measure the solar spectral irradiance in the 165 - 3000 nanometer range with high spectral resolution.

Lens, Switzerland

History

Lens is first mentioned in 1177 as de Lenz.

Geography

Lens has an area, as of 2009, of 13.9 square kilometers (5.4sqmi). Of this area, 5.07km2 (1.96sqmi) or 36.4% is used for agricultural purposes, while 5.48km2 (2.12sqmi) or 39.4% is forested. Of the rest of the land, 2.74km2 (1.06sqmi) or 19.7% is settled (buildings or roads), 0.1km2 (25 acres) or 0.7% is either rivers or lakes and 0.46km2 (0.18sqmi) or 3.3% is unproductive land.

Of the built up area, housing and buildings made up 11.2% and transportation infrastructure made up 4.0%. while parks, green belts and sports fields made up 3.8%. Out of the forested land, 33.6% of the total land area is heavily forested and 5.8% is covered with orchards or small clusters of trees. Of the agricultural land, 0.4% is used for growing crops and 11.6% is pastures, while 9.1% is used for orchards or vine crops and 15.3% is used for alpine pastures. All the water in the municipality is in lakes.

Fresnel Lens Solar Distilled Water from the Sun

Fresnel Lens solar water filtration systems offer an off grid option to clean water This solar distiller can deliver .5 GPH The Fresnel lens concentrates sunlight to a common focal point that creates a steam boiler allowing for rapid distillation with the sun.
http://greenpowerscience.com/
If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water. Distilled water is not magic, if you add a splash of milk to tea made with distilled water, you now have 10x the calcium of regular mineral water.
http://www.eves-best.com/distilled-water-myths.htm
Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. ...

GIANT FRESNEL LENS TROUGH MIRROR
http://www.greenpowerscience.com/
The max power was 20 watts, pretty weak. The treadmill motor produced about 25v no load and was able to get the GTI working:-) BUT it did not last long. This should be much stronger. I rushed today because it was our first REAL day of sun in over 1 month.
MORE TO FOLLOW. The Boilers were all wrong, this was about 1% efficient. Shot 3 hours of video, only 2 minutes worth showing. THAT TYPE OF DAY.

Solar Cooking Fresnel Lens Dutch Oven

First attempt to cook with a dutch oven and a fresnel lens. Worked okay, took three hours to make. Good for small container cooking, don't know if it will work on larger kettles. Fresnel lens and Dutch oven purchased thru A PlusSurvival in Santa Ana. At the end of cooking when I was putting it in the bowl the front leg gave out and it all went on the ground, the second one I cooked the day after this was chicken and dumplings. That was great...

My "Solar Scorcher" project was originally inspired by Dan Rojas of GreenPowerScience: http://youtu.be/JkgFk15uBxw (Fresnel LensGiant "Big Daddy")
Project History & More Info:
These TV's are old, extremely heavy, and are breaking down on people everywhere. They usually cost more to fix than they could be sold for, so people are begging you to come take them away for free!
I usually find mine on the classified ads under the "free" section, but they are also common on the sides of streets and alleyways where people have left them for trash.
PLEASE NOTE: These lenses are found in "rear-projection" televisions and not all are the same. Some are discolored, and some concentrate to a beam rather than a point. The particular screen I found was a crystal clear acrylic lens that focused to a point. It may have been luck that I found it on my first try, because 3 TV's after that all had lesser grade lenses, but still produced enough heat to melt zinc. Just FYI! You can also see http://youtu.be/xExXjXm0YV0 for examples of these different lenses.

I use a large fresnel lens to test the effect of concentrated sunlight on a solar cell. To keep the solar cell cool I immerse it in mineral oil. I measure the voltage, current and the temperature. But I also test it without the cooling and sure enough, the solar cell is destroyed by the concentrated sunlight. The fresnel lens is one I got from a rear projection TV.

This is the same solar stirling engine with a strong Fresnel Lens. The steel wool adds power to the stirling displacer piston as the light has a good focal target INSIDE the glass chamber Dramatically increasing efficiency. This is very important as most Stirling Engine lose 50% of their heat into the surrounding air. A vacuum would be even better. Also, because the glass chamber easily removes with a rubber O ring fitting, air can be replaces with a custom heat exchange gas.

SolarFresnel Lens and a Tevana Tea vacuum container + steel wool nanoparticles. Superheatedhttp://www.greenpowerscience.com/ steel wool creates nanoparticle surface structure.
The steel wool has a vast surface area, when superheated dry, the smooth shiny surface structure opens up creating structural crevices less than 100 nanometers that act as nanoparticles. Any previously mirrored metallic object that is dulled with heat alone has this micro structure. This is different than sanding. The direct contact with the aqueous solution allows for optimal heat transfer from the heated metal surface to the water. Steel wool is a good choice over mud bath nanoparticle suspensions as the skeletal structure allows for enhanced area coverage in 3 dimension vs that of a 2 dimensional mud bath.
Green Job CareerTraining. BOILING WATER. I am working in a very efficient boiler that can retain more heat. The concept can also be used in the large Stirling Engine. If very little heat escapes from the boiler or displace side of a Stirling Engine, the efficiency and power will go way up.

Finally! A working mini solar tower powered by a fresnel lens that turns a turbine, a paper turbine. It's nowhere near powerful enough to turn a PC fan.

If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water.

http://www.eves-best.com/distilled-water-myths.htm
Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. For the rest of the world who usually ingest 15x the sodium recommended, distilled water leaches salt first. ONLY IF you are salt deprived (extremely rare) will distilled water leach excess potassium and or calcium.
You would need to drink about 2 gallons in 10 hours for there to be a problem.
If heavy sweating, water of any kind is only a thirst quencher or temporary fluid fix. Most people can afford 7 pounds of sweat (near gallon) replaced with only water before electrolytes become an issue. At that point, electrolytes are needed regardless of water type ingested. Mineral water has very small trace minerals and represents a small fraction of where K, Na, Ca is absorbed in the body. For you to get your average daily requirements of Ca and K from water alone, the water would taste terrible.

Fresnel Lens Solar Distilled Water from the Sun

Fresnel Lens solar water filtration systems offer an off grid option to clean water This solar distiller can deliver .5 GPH The Fresnel lens concentrates sunlight to a common focal point that creates a steam boiler allowing for rapid distillation with the sun.

If you are concerned, add 10mg Na to each liter. Also, eating food with water, all minerals are mixed with fluid in the stomach converting distilled water into mineral water. Distilled water is not magic, if you add a splash of milk to tea made with distilled water, you now have 10x the calcium of regular mineral water.

Distilled water is very good for you. The only areas it may cause a problem is developing nations that have near famine conditions. For the rest of the world who usually ingest 15x the sodium recommended, distilled water leaches salt first. ONLY IF you are salt deprived (extremely rare) will distilled water leach excess potassium and or calcium.
You would need to drink about 2 gallons in 10 hours for there to be a problem.
If heavy sweating, water of any kind is only a thirst quencher or temporary fluid fix. Most people can afford 7 pounds of sweat (near gallon) replaced with only water before electrolytes become an issue. At that point, electrolytes are needed regardless of water type ingested. Mineral water has very small trace minerals and represents a small fraction of where K, Na, Ca is absorbed in the body. For you to get your average daily requirements of Ca and K from water alone, the water would taste terrible.

This is our extreme solar fresnel lens in action. I have a GIANTLens that is even stronger but this spot fresnel lens works perfect for heating metal using the sun.

The saw blade is solid steel. Total time through the blade was 3 minutes. All other melts were realtime.

The max power was 20 watts, pretty weak. The treadmill motor produced about 25v no load and was able to get the GTI working:-) BUT it did not last long. This should be much stronger. I rushed today because it was our first REAL day of sun in over 1 month.
MORE TO FOLLOW. The Boilers were all wrong, this was about 1% efficient. Shot 3 hours of video, only 2 minutes worth showing. THAT TYPE OF DAY.

Solar Cooking Fresnel Lens Dutch Oven

First attempt to cook with a dutch oven and a fresnel lens. Worked okay, took three hours to make. Good for small container cooking, don't know if it will work on larger kettles. Fresnel lens and Dutch oven purchased thru A PlusSurvival in Santa Ana. At the end of cooking when I was putting it in the bowl the front leg gave out and it all went on the ground, the second one I cooked the day after this was chicken and dumplings. That was great...

Fresnel lens

The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. A Fresnel lens can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances.

History

The idea of creating a thinner, lighter lens by making it with separate sections mounted in a frame is often attributed to Georges-Louis Leclerc, Comte de Buffon. The marquis de Condorcet (1743–1794) proposed grinding such a lens from a single thin piece of glass.
French physicist and engineer Augustin-Jean Fresnel is most often given credit for the development of the multi-part lens for use in lighthouses. According to Smithsonian magazine, the first Fresnel lens was used in 1823 in the Cordouan lighthouse at the mouth of the Gironde estuary; its light could be seen from more than 20 miles (32km) out. Scottish physicist Sir David Brewster is credited with convincing the United Kingdom to adopt these lenses in their lighthouses.
